There was research some time ago (jeez, 10 years ago...) [0] [1] that used video and... computer vision algorithms to detect a person's heart rate without any devices. Wondering if it could be used here i.e. use your webcam instead of an external hardware sensor?
Other thing - would you be open to publishing/sharing your algorithm / esp32 code (on Github or as a blog article)?
